17 Things You Should Always Do Before Boarding Your Flight

14. Review Entry and Exit Requirements One More Time

Border rules can change overnight. Before you leave for the airport, double-check your destination’s entry and exit requirements—even if you’ve researched them already. Some countries require arrival forms, proof of accommodation, return tickets, or customs declarations. Others may have specific rules about prescription medications, duty-free limits, or digital vaccine passes. A last-minute review can save you from surprises at immigration or customs and speed up processing time. Keep all required documents (digital and printed) easily accessible. A quick re-check could be the difference between breezing through security or being turned around at the gate.
